If your 2010-2012 Silverado 1500 is suffering from frustrating no-start conditions, stalling, or erratic engine performance, a failing Fuel System Control Module (FSCM) is a very likely culprit. As a technician with over two decades of experience, I’ve seen countless trucks come into the shop with these exact symptoms. This isn’t just a part; it’s a direct, reliable solution to restore your truck’s performance and dependability. The FSCM, or fuel pump driver module, is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to a host of problems.
The biggest challenge with replacing this module has always been the required trip to the dealership for programming. We eliminate that expensive and time-consuming step. This module arrives at your door fully programmed with the latest GM software updates, specifically matched to your truck’s Vehicle Identification Number (VIN). This means no extra costs, no appointments, and no need for specialized scan tools. It’s a true plug-and-play fix that gets you back on the road faster.
Is Your Truck Showing These Symptoms?
- ✔ Engine cranks but refuses to start.
- ✔ Vehicle starts and then stalls unexpectedly.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Noticeable loss of engine power, especially under load.
- ✔ An active Check Engine Light with codes like P069E (Fuel Pump Control Module Commanded OFF), P0230 (Fuel Pump Primary Circuit Malfunction), or U0109 (Lost Communication With Fuel Pump Control Module).
Case Study: A Tricky Diagnosis
A customer brought in an ’11 Sierra with a classic “crank, no start” issue. Another shop had already replaced the fuel pump, but the problem persisted. After spending a few minutes with a scan tool, I saw no communication with the FSCM (a U0109 code). These modules, mounted on the frame rail, are exposed to years of moisture, salt, and road debris, causing internal corrosion and failure. We installed a VIN-programmed module, and the truck fired right up. The customer had wasted hundreds on the wrong diagnosis; this part was the real fix all along.
A Straightforward Guide to Installation
Installing your new 2010-2012 Silverado 1500 Fuel System Control Module is a job most DIYers can handle in under an hour with basic hand tools. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your truck’s battery before starting any electrical work.
- Locate the Module: On most Silverado and Sierra trucks, the FSCM is mounted to the driver’s side frame rail, typically near the spare tire.
- Disconnect: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly to avoid breaking them.
- Unbolt the Old Module: Remove the bolts or nuts holding the FSCM to its bracket on the frame. It may be rusty, so a little penetrating oil can help.
- Mount the New Module: Bolt your new, pre-programmed FSCM into place. Ensure it’s secure.
- Reconnect and Test: Plug the electrical connectors firmly into the new module. Reconnect your battery, cycle the key a few times to prime the system, and start the engine.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives 100% programmed to your vehicle’s VIN. It is ready for installation right out of the box, saving you a trip to the dealer.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive your VIN to program it.
Is this the same as a fuel pump driver module (FPDM)?
Yes, Fuel System Control Module (FSCM) and Fuel Pump Driver Module (FPDM) are different names for the same component. This part serves that function.
What if my original part number is different?
This module is a direct replacement for several part numbers, including 20791901, 20827745, and 20850927. As long as your vehicle is on the compatibility list, this module will work once programmed to your VIN.
Could a bad FSCM drain my battery?
It’s possible, but not common. More typically, a failing FSCM will cause starting and running issues. If the module has an internal short, it could potentially cause a parasitic draw, but the primary symptoms are fuel-delivery related.
